Top 50 cities in the world

What are the top 50 cities in the world? Tripadvisor.com has recently released a list based on its readers' votes and on this week's ATW Travelradio Australia podcast I list and discuss the poll results. Also on the show Michael Cervin reports on his visit to Fredericksburg, Texas, an interesting German heritage town in the hill country which I also had the pleasure of spending a few nights in some years ago. Our European reporter Frances Beasley travels a 'long and winding road'. US author Rachel Friedman chats about her book 'Guide to Getting Lost' (I don't need a guidebook for that, I'm quite good at it without help!)
